Get the RF 24-240 because you mentioned the magic keyword travel! Use the 50mm f/1.8 for astro now and consider a wider fast astro prime later. For macro, you need to find something acceptable as RF 24-240 ain't a macro lens. The RF 35mm macro has only 0.5x magnification and costs a lot for a 35mm lens.

When the Canon 24-105mm II came out I was able to test two copies against two copies of the Sigma 24-105mm. A few observations: Autofocus on the Canons was more precise, but the Sigma was good for the Art range and the f/4 maximum aperture meant that slight misfocuses did not result in an out of focus image. Overall a win for Canon.Buy Canon EF 24-105mm f/4L IS USM Lens featuring EF-Mount Lens/Full-Frame Format, Aperture Range: f/4 to f/22, One Super UD Element, Three Aspherical Elements, Optical Image Stabilization, Super Spectra Coating, Ring-Type Ultrasonic Motor AF System, Optical Image Stabilizer, Weather-Sealed Construction, Rounded 8-Blade Diaphragm.
